Ruud Heat Pump control wiring

Ruud Heat Pump control wiring

Ruud Heat Pump control wiring

(OP)
I just installed a 5 ton package unit in my home. Of course the control voltage wiring color code is altogether different, so I am trying to find out what the different terminals on the circuit board control. On the board I have the following terminals: C,C,D,Y,B,R. I have figured out enough to get the A/C working, but I am having a problem with the heat pump and auxilary heat. Any help in understanding what these terminals control would be GREATLY appreciated. The package unit is a Ruud, RQNJ series.
Thanks!

Thanks for the reply. I have been to the link you that you attached. This is basically the same schematic that I have in the manual that came with the unit. Problem is.... it doesn't show the current routing through the circuit board. I need to know what the terminals on the board control, i.e. does the green control wire control the fan relay, does the white wire control aux. heat or reversing valve, etc. Do you think if I get the numbers off the board itself that I can find a schematic on the internet?

Thanks,
Robert

Does the circuit board have a name on the diagram like "the defrost control" or "The stat sub base"
